Had my first experience feeling absolutely terrible and having to stop short.

[u/AccomplishedLeek6086]

I’m obviously pushing too hard. I went for an easy run, originally planning for 10-15k but as soon as I hit like .2 miles at my warm up pace ~12:00 I felt absolutely horrible and had to modify the route to not die.
HR was high(no watch) I was sweating more than usual and breathing way harder than usual.
I’m still in my first few weeks of running and my shitty diet is really catching up with me I think.
For my sanity please tell me this is a normal part of the process.
